Patch #40798
closed
Optimize Version model
Added by Go MAEDA about 1 month ago. Updated about 1 month ago.
Description
The attached patch improves the performance of several methods in the Version model such as Version#issues_count, FixedIssuesExtension#completed_percent, FixedIssuesExtension#closed_percent, and FixedIssuesExtension#issues_progress.
These methods use count method to get the total number of fixed issues in the version. It performs an SQL count query every time it is called. This patch replaces count with open_count + closed_count in order to use cached values instead of performing SQL count queries.
The change has an effect on Gantt as well as Roadmap.
